tickle is not that great, to my knowledge. I always get 140+ on it. I just tried the one at www.iqtest.com and it seemed a bit better, though a bit more limited in types of intelligence. They measure IQ on a bell curve, though, relative to everyone else who has taken the test, which is a good way of doing it. I got 133, along with 2.3% of everyone else who has taken the test, so I'm gifted, but not a genius.
Interesting things, IQ tests, good for boosting ego sometimes, and moreover for challenging the brain a bit. Not terribly meaningful, though, even the official ones.

But as for pneumothorax...
A collapsed lung is not fun. Your lungs work on the principle of nature abhorring a vacuum. Your lungs are in a sort of bag attached to the insides of your ribs. When you breathe in, the action you are actually doing is expanding your rib cage. This makes the "bag" bigger, and therefore pulls your lung out and makes it bigger... Therefore sucking air into your body from the atmosphere.
So if the bag is "popped," that destroys the vacuum, letting fluid into the bag. That's what the white stuff you see in the right lung in the radiograph is. When there is no longer a vacuum, there is nothing to pull the lung out, so the lung smooshes in on itself. And therefore, you can't use it anymore. Considering the volume of air your body needs just to function at rest, it is a bad thing to have only one functioning lung. =P_________________fight
